US - No new positive results for Porcine Delta Corona virus (PDCoV) have been detected in the US in the last week, so the total number of positive samples so far remains at 382 from pig farms in 17 states.

For the latest weekly report - for the week of 7 September in a report dated 17 September from the USDA Animal Health Inspection Service and made available by the American Association of Swine Veterinarians (AASV) - no pig farms (termed "swine accessions") have tested positive for the PDCoV.

The National Animal Health Laboratory Network (NAHLN) began collating testing data on PDCoV for the week of 30 March 2014. So far, 5,827 accessions have been tested, 281 in the most recent week reported, so the overall percentage found positive is 6.6 per cent.
